According to the Centers for Disease Control and Prevention, about 10,000 people could be at risk of hantavirus- a fatal respiratory disease contracted from urine, saliva and feces of infected deer mice that has been traced to cabins in Yosemite National Park this summer.

The Los Angeles Times reported:

• Park officials said Friday that they had sent letters and emails to about 3,100 people who reserved one of the 91 "signature tent cabins" in the park's popular Curry Village between June 10 and Aug. 24. The CDC alert — issued through its health advisory network, which reaches healthcare providers as well as health departments — said that an estimated 10,000 people stayed in the tents during that time.
• Six confirmed cases of the rare, rodent-borne disease have been linked to the park, officials said. Four have been traced to the signature tent cabins; the remaining two were still under investigation, Yosemite spokesman Scott Gediman said Friday.
• The letters warn recipients to seek immediate medical attention if they or anyone in their party start to show symptoms of the disease.

According to the CDC, early symptoms include:

• Fatigue, fever and muscle aches, especially in the large muscle groups—thighs, hips, back, and sometimes shoulders. These symptoms are universal.
• There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. About half of all HPS patients experience these symptoms.
• Four to 10 days after the initial phase of illness, the late symptoms of HPS appear. These include coughing and shortness of breath, with the sensation of, as one survivor put it, a "...tight band around my chest and a pillow over my face" as the lungs fill with fluid.
